Problems solved by technology

However, in such a large and complex environment as a ship, there are many types of detectors and fire linkage equipment, the inspection cycle is long, and the internal data processing software structure of the system is complex, and the reliability of the alarm system is reduced accordingly, so it is not suitable to use centralized intelligence type fire alarm system

Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings.

[0017] Concrete steps of the present invention are:

[0018] (1) The present invention designs a kind of distributed intelligent fire alarm system based on fuzzy control for the Kyiv ship, and the cabin of the ship is divided into three categories according to the degree of fire risk, the first category: control station, class A machinery space, ammunition cabin and missile The cabin is a cabin with a high fire risk, and the value is set between 0.7-0.9; the second category: the electronic equipment room and service spaces with a relatively high fire risk are cabins with a fire risk, and the value is set between 0.5-0.6; Category III: Stairways and passageways, accommodation spaces, service spaces with less fire risk, other machinery spaces and open deck spaces are cabins with less fire risk, and the value is set between 0.1 and 0.4;

[0019] (2) The fuzzy intelligent c...

Abstract

The invention relates to a ship fire extinguishing system cascading failure evaluation method for distributed intelligence control. The method carries out distributed intelligence control on an existing ship fire extinguishing system on the basis of fuzzy control, builds cascading failure indexes of the ship fire extinguishing system and judges the cascading failure situation. The method includes the steps that a ship cabin is divided into three kinds according to the fire danger degree, information of four parameters undergoes normalization preprocessing, a fire alarm grade evaluation result of the ship cabin is obtained, and a main machine judges the alarm degree of the ship cabin. The method can improve reliability and accuracy of an automatic fire alarm system of the ship cabin, improve the ability to avoid cascading failures and similar extreme disasters, and reduce occurrence of the extreme disasters. According to the method, due to the fact that fire characteristics of the ship cabin are taken into consideration, chain alarm is achieved. Therefore, the method can well facilitate ship environment, improve ship safety and enhance practicality.

Description

technical field [0001] The invention relates to a method for evaluating the cascading failures of the distributed intelligent control ship fire-fighting system by performing distributed intelligent control on the existing ship fire-fighting system based on fuzzy control, establishing a cascading failure index of the ship's fire-fighting system, and judging the cascading failure situation. Background technique [0002] At present, the research on automatic fire alarm system at home and abroad is mainly divided into two stages: [0003] The first stage is the non-intelligent fire alarm system. The addressable automatic fire alarm system that appeared in the late 1970s and the analog addressable automatic fire alarm system that appeared in the early 1980s are the most typical applications. Functional multi-line fire alarm system and a bus-type fire alarm system controlled by a microprocessor. For example, the CPF series fire automatic alarm system produced by NITTAN Company, a...
